TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 398,587, dated February 26, 1889.

Application filed August 13, 1886. Serial No, 210,782. (No model.)

To (1// 1/7/0111 it may concern.-

llc it known that 1, JOHN S. DOVE, Jr., a citi zen ot' the lfnited States, residing in the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Im- .herein described and claimed, whereby the upper-case and spacing levers may be operated by the foot. 3y these means the hands from striking the key ll.

It will be seen that when itis desired to operate the upper-case lever C the treadlc K is moved by the foot, whereby, by means 01? the rod J, lever H, lever G, and rod F, said lever is depressed, and the hand thus relieved \Yhen it is desired to operate the spacing-levers E, the treadle K are free to operate the several type-keys without being required to depress ormanipnlate the key of the upper-case lever or the bar of 5 the spacing-levers.

Referring to the drawings, A represents a table for supporting a type-writing machine, which, excepting some slight changes neces sary to adapt it to my invention, maybe of well-known constructionsuch as, for i11- stance, that of the Remingtonto which, however, I do not limit the invention.

15 represents the key of the upper-case lever C, and D represents the connecting-lmrof the spacin g-levers E, said levers having connected with them depending rods F F, which pass through openings in the table A, and are attached to levers G G, which are mounted on hangers or cars G on the under side of the table. The levers G G are connected bylinks or straps with leversll ll, which are mounted on hangers or cars H on the under side of the table. The levers H H are connected by means of rods J J with foot-treadles K K, the latter being mounted on a rod, L, which is attached to the legs of the table at the lower end thereof.

is moved by the foot, whereby, by means of the rod J, lever 11, lever G, and rod 1:", said levers are depressed, and thus the hand is relieved from striking the spacing-bar D.

The parts are restored to their normal positions by means of springs J which are attached to the connecting bars or rods J J and under side of the table. The springs are preferably connected to the bars J .l by means of an adjustable sleeve, R, on each of said bars, which sleeve is secured thereon by the screw S, as shown in the drawings.

The levers H H pass through slotted guides M, which depend from the table A, and contain buii'ers N, of rubber or other elastic or flexible material, said butters being above and below the respective levers H H, and attached to screws P, which are fitted to crossbars in said guides, whereby the buffers may be set with nicety in relation to the throw of the levers H H, the object of said buffers being to stop or limit the motions of the levers H H, thus preventing strain on the levers C E and also obviating noise when the levers H H strike said stops.

Having thus described my invention, what- I claim new, and desire to secure by Letters Patent, is

In a type-writing machine, an upper-ease lever, in combination with a foot-t-readle and intermediate depending rod, levers, and connecting-rod, one of said intermediate levers having a guide with butters, all substantially as and for the purpose set forth.
